Title: Process for the Oligomerization of Olefins.
Inventor: BARNETT KENNETH WAYNE
IPC: C07C2/34
Filed: 1969-04-08
Abstract: 1,196,889. Oligomerizing olefins. SHELL INTERNATIONALE RESEARCH MAATSSCHAPPIJ, N.V. 8 April, 1969 [9 April, 1968 (2)], No. 17880/69. Heading C5E. [Also in Division B1] Mono-olefins are oligomerized by contact with a heterogeneous catalyst comprising a reduced nickelocene and a solid inorganic support. The catalyst may be made either by contacting the support with nickelocene in the presence of hydrogen, or by applying #-cyclopentenyl-#-cyclopentadienyl-nickel directly to the support. Many suitable supports are listed. In examples ethylene, propylene and 1-butene are oligomerized, the supports being silica/ alumina (25% Al 2 O 3 ), tungstic oxide/alumina (10% or 12% WO 3 ) or silica/alumina/tungstic oxide (10% WO 3 ). The products contain higher proportions of trimers and tetramers than using a comparative catalyst in which the nickelocene is not reduced, but the main single oligomer product is the dimer.

IPC: H01H33/92
Filed: 1954-06-18
Abstract: 778,909. Liquid-blast switches. REYROLLE & CO., Ltd., A. Sept. 15, 1955 [June 18, 1954], No. 17906/54. Class 38(5) An injector forces oil into the turbulator 11 enclosing the arcing zone of a liquidblast switch during the closing movement of the contacts to reduce any tendency to prearcing. If the moving contact 14 is tubular and longitudinally withdrawable for contact separation, an injector may inject liquid into the moving contact and thence into the turbulator during contact separation to prevent cavitation. In Fig. 1 the injectors 20, 21 are separate and each comprises a piston 23 biased by a spring 24 in a cylinder 22 having a non-return inlet and outlet valves 25, 26, the outlet valves 26 being connected to a fixed pipe 19 over which the contact 14 is movable. When the switch is opened by the anticlockwise movement of the lever 15. the spring 24 of the injector 20 moves the piston to force liquid into the contact 14 providing the arc-generated pressure in the turbulator is not too high. During this opening movement, the lever 15 moves the 'piston of the injector 21 to compress the associated spring 24 which on the subsequent closure of the contacts, forces liquid from the injector 21 into the contact 14 and turbulator. In a modified arrangement, Fig. 2 (not shown), a single double-acting piston-and-cylinder injector is used. In this case a spring injects liquid during contact separation, but injection during closing is effected positively by the movement of the piston by the switch operating mechanism. Specification 778,908 is referred to.

IPC: C07C1/207
Filed: 1938-06-16
Abstract: 506,464. Organic acids and olefines. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPIJ. June 16, 1938, No. 17968. Convention date, Jan. 21. [Class 2 (iii)] Carboxylic acids and unsaturated compounds are prepared by bringing hydroxyketones or hydroxyaldehydes into contact with a non- basic catalyst at above 160‹C. but below the temperature of substantial decomposition. Thus, acetic acid and isobutylene are obtained by passing diacetone alcohol at 200-350‹ C. over a catalyst made by calcining a mixture' of phosphoric acid and a siliceous material, such as kieselguhr. Polymerization of isobutyleno to di-isobutylene takes place if the free acid content of the catalyst is high. Water is added to the reaction products so that on distillation azeotropes of mesityl oxide and diisobutylene with water are removed. Propionic acid and tertiary amylene may be obtained from the condensation product of methyl-ethylketone containing 8 carbon atoms, one hydroxy group and one ketonic group. Acetic acid and normal butylene are obtained from 4-hydroxy pentanone-2 with simultaneous -production of methyl propenyl ketone, acetic acid and ethylene from dimethyl ketol and formic acid and propylene from aldol. Other catalysts may be used such as silica gel, zinc chloride, ferric chloride, ferrous sulphate, sodium acid sulphate, sulphuric acid and boryl phosphates. Specification 448,313 is referred to.
